Packaging Applications

Package Single Version
ZK doesn't support to run 2 different versions in a single web application. Please be sure you package only one single version of ZK into a WAR.
2023-03-02 09:21:44 [INFO ] ConfigParser:116 - Ignore jar:file:/Users/yourName/.m2/repository/org/zkoss/zk/zkex/9.6.3/zkex-9.6.3.jar!/metainfo/zk/config.xml
Cause: ZK version must be 9.6.3 or later, not 9.6.0
This is a not-recommended practice. Since ZK stores its configurations (parsed from zk.xml) as a static object, all your zk applications in the same application server will have the same configurations. If you change a configuration (library property), it will affect all zk applications.
Package as EAR
An EAR file contains one or more JAR and WAR.
